This study is aimed at validating the French version of the Effort-Reward Imbalance Questionnaire for Teachers. The instrument was pretested before being administered in a large-scale study with elementary school teachers. Dimensionality of the instrument was examined using the bifactor exploratory structural equation modeling (ESEM) framework. The bifactor ESEM model showed the best fitting indices and parameters. Importantly, results suggested the existence of a continuum for ERI data concerning elementary teachers. The instrument showed concurrent validity with several measures of mental health, job satisfaction and work-life balance.
